DETAILED DESCRIPTION

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The embodiments set forth in the following description of exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of apparatuses and methods consistent with aspects related to the present disclosure as recited in the appended claims.

In some embodiments, near field communication (NFC) may be supported by an application of a mobile phone. After a user gets a room card at a hotel, the room card may be simulated by the mobile phone. Then, a door may be unlocked using the mobile phone. However, the room card of the hotel may be encrypted and may not be simulated automatically using NFC. Furthermore, it still requires manual participation of both hotel staff and the guest and may take a long time. The guest may run late due to a queue during rush hour. In addition, a physical room card is still required as well, and there may be a risk such as that the room card is lost, damaged, etc.

In some embodiments, a door of a room at a hotel may be unlocked through face identification or fingerprint identification. A guest may enter face or fingerprint information when checking in at the hotel reception. Then, the guest may unlock the door and enter the room using a camera or a fingerprint lock at the door. This process requires additional entry of face or fingerprint information at check-in and, thus, participation of both hotel staff and the guest, which may take a long time.

In view of the above, embodiments of the present disclosure provide an authentication method for a server of a hotel, an authentication method for user equipment (UE) of a guest checking into the hotel, and an authentication method for door lock equipment of the hotel.

FIG. 1 is a flowchart of an authentication method 10, according to an exemplary embodiment. The authentication method 10 may be used in a server of a hotel. The server may communicate, through a web page or an application, with UE of a user, e.g., a guest who is to check into the hotel. The server may also communicate, through a local network of the hotel, etc., with door lock equipment of a room of the hotel. As shown in FIG. 1 , the authentication method 10 includes the following steps.

In S11, check-in information sent by UE of a guest checking into the hotel is acquired. The check-in information includes information on the guest checking in and a check-in period.

In an embodiment, the guest may book the hotel using a web page or an application in the UE. The server of the hotel may acquire check-in information of the guest. Check-in information may include at least information on the guest, such as a name, an ID number, etc. Check-in information may further include a check-in period, such as a check-in time and a check-out time.

In S12, information on a room of the guest is determined based on the check-in information. The information on the room is sent to the UE.

In an embodiment, the check-in information is acquired, and then, the information on the room of the guest may be determined. For example, any available room may be displayed according to a filter condition such as a number of guests checking in, check-in periods, etc. The information on the room of the guest may be determined by letting the guest select the room. Also for example, the information on the room of the guest may be determined by a hotel according to a number of guests checking in, check-in periods, etc. After the information on the room of the guest is determined, the information on the room may be sent to the UE of the guest. Accordingly, the guest may conveniently learn the room to check in. The information on the room may include a room number of the room, a location of the room, etc.

In S13, unlocking information is determined based on the check-in information. The unlocking information is sent to at least one of the UE or door lock equipment corresponding to the information on the room. The door lock equipment is configured to authenticate the guest based on the unlocking information during the check-in period. The unlocking information may be invalid other than during the check-in period.

In an embodiment, once check-in information is determined, to allow a guest to enter a booked room conveniently without having to go through service at the reception upon check-in, unlocking information may be sent to at least one of UE of the guest or door lock equipment of the booked room. Accordingly, during a check-in period, the guest may be authenticated by the door lock equipment and enter a room. Therefore, a labor cost and a waiting time may be reduced greatly, improving efficiency, and a guest may check into a hotel safely and quickly.

FIG. 2 is a flowchart of an authentication method according to an exemplary embodiment. Referring to FIG. 2 , S13 (FIG. 1 ) may include the following steps.
